WILLIAM BEAOH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN PRIVY-SEAT COVERS.

To all whom it may concern:

Be it known that I, WILLIAM BEACH, 0f th city of Philadelphia, in theState of Pennsylvania, have invented a new and useful Improvement inPrivy-Seat Covers; and I do hereby declare tha-t the following is afull,

`clear, and exact description ofthe construction and operation of thesame, reference be- Aing had to the accompanying drawings, inakin g apart of this specification, in which--` Figure 1 is a front elevation ofa privy-seat partly broken out, having my improvement `applied thereto;and Fig. 2. a vertical transverse section of the saine, like leters ot'reference indicating' the saine parts when in both figures. y

The covers or lids of pri vy-seats bein g generally either loose orhinged upon the upper side of the seats, the holes are consequentlyoften left open, and besides the free escape of effluvia, ready accessis afforded to house-flies and mosquitoes for breeding therein. `Thelids,

`when closeddown, condense the rising moist- `with the usual hole ct; B,the lid or cover, and

O t-hemtreadle. The lid or cover B is rigidly fixed toa shaft, b', whichextends across and close beneath the seat A, and has journals which turnin appropriate holes made iu the front and back of the supports of theseat. The front journal projects 4through its support, and has fixed onits end a short arm, d, which is parallel to or projects from theshaft bin the same plane and direction as the lid B. rIhe free end of this armis jointed to a vertical rod, e, and the lower end of said rod isjointed to the end c of the treadle C, and the opposite end, c2, of thelatter is hinged to the tloor of the privy. y'

On the rear portion of the shaft b' a grooved pulley, j', is fixed,whichcarries a cord,to which is suspended a weight, G, in 'such a manneras to overbalance the weight of the lid B, rod e, arm d, and treadleO,as represented in the drawings. I

Operation: When a person steps upon the treadle O the latter will bebrought down parallel with the door of the privy, as indicated by thedotted lines w, Fig, 1, and at the saine time the lid or cover B will`be openeddownward to the vertical position indicated by thel dottedlines a, lifting the weight G upward, and immediately on stepping off ofthe said treadle O the weight G will sink, and, 'consequently, turn thelid B upward against the under side of the seat A, or into its normalposition, and thus close the hole af, as required.

A spring may be substituted for the weight G and pulley f; but thelatterare more elfect- I ive for the purpose, and are less liable to get outof order. Also, a pulley and cord inay be substituted for the arm d androd e, if preferred:

- What I claim as my invention, and desire g to secure by LettersPatent, is-

The cover or lid B, hinged to the under side of the privy-seat, andoperated by means of a` WILLIAM BEACH.l
